How It Works.

Like the Like ZB-545M SOHO Max, ZB-545X SOHO Xtreme, ZB-645SL-CM, and ZB-645SL, this Wi-Ex zBoost SOHO ZB-545 captures the reliable cellular singular from outside your home or business with an omnidirectional exterior antenna. The internal antenna then rebroadcasts it indoors via the indoor unit. The coverage area for this unit is up to 2,500 square feet. There is a 64 dB system gain.

  2. Increases 3G data performance.
  3. Decreases dropped and unclear voice calls.
  4. Allows for multiple simultaneous users and devices.
  5. Works with all brands of mobile devices.
  6. Automatically regulated – this unit operates at maximum gain and requires no manual adjustments.

zBoost SOHO boosts up to 2,500 square feet. It is ideal for small homes and buildings. It includes omni external antenna CANT-0033, omni internal antenna CANT-0034, and RG-6 cable.

Set-up requirements and instructions necessary for maximum performance:

  1. The outdoor external antenna and indoor rebroadcasting antenna need to be at least 15 vertical feet from each other.
  2. Less than 15 vertical feet of distance between the two antennas will result in decreased performance.
  3. Increasing the distance will increase the performance of the zBoost ZB545.
  4. The maximum distance between the antenna should not exceed 40 feet.
  5. The outdoor external antenna needs to be at least 3 feet above any metal.

Step 1: Mount the external antenna.

  1. Choose a location based on your mobile devices’ signal strength.
  2. Choose an area with the best signal strength.
  3. If the external antenna is place in an outdoor area that receives low signal strength the indoor signal will not be strong and coverage area will be diminished.

Step 2: Mount the indoor rebroadcasting antenna.

  1. Place the indoor rebroadcasting antenna where you want to create increased signal strength.
  2. For the widest possible signal strength coverage place the indoor rebroadcasting antenna in the middle of a room.
  3. The signal broadcasted from the antenna is omnidirectional allowing the unit to be mounted on a vertical wall or placed horizontally.
  4. Do not place the unit on the floor or near other cords, metal, or other wireless devices.
  5. The indoor rebroadcasting antenna features a detachable base unit that can be mounted with screws (screws not included).

Step 3: Connect the external and internal antenna with the provided white coaxial cable.

  1. Run the cable from the external antenna to the indoor rebroadcasting antenna through a window.
  2. Coaxial cable extensions are available in 15 foot lengths (Part: YX030-15W).
  3. Coaxial cable exceeding 65 feet in length is not recommended.
  4. An 8-inch window entry cable is available for purchase (Part: YX030-08W).

Step 4: Connect power supply to the internal rebroadcasting antenna and check system operation.

  1. Plug the power supply into the internal rebroadcasting antenna.
  2. Plug the power supply into a wall power outlet.
  3. After initial power up the LED light will cycle red, green, and orange for 30 seconds.
  4. After the LED light cycles for 30 seconds, the LED will flash green to indicate the strength of the signal, and then will be followed by a solid green light.
  5. If a solid green LED light is not observed refer to the “Base Unit LED Indicators” section of the user manual for further instruction.
  6. Adjustments may be required to optimize the performance.
  7. Check that the zBoost system is in place and fully connected through your coverage zone.
  8. If increased signal strength is observed on mobile devices the unit is working.
  9. Signal strength can be affected by outdoor signal level, building construction, and antenna placement.
  10. Coverage can be reduced by interior walls and ceilings.

Step 5: Enjoy increased cellular signal strength in your home or business!
